Yes. Let's look at PEMDAS. Parentheses, Exponents, <em>Multiplication</em>, <em>Addition</em>, Subtraction. As we can see, multiplication comes first. In -2 + 3x, reading it from left to right, we see the addition symbol first, but because we're supposed to do multiplication, we have to do the 3x first. The same goes for 3x + (-2).
Yes. The two expressions -2 + 3x and 3x + (-2) are equivalent.
Hope this explanation helped you out. :)
Answer:
There is not enough info to be able to answer this question properly.
Step-by-step explanation:
For this type of equation, you will need to use point-slope formula [Y-y1=a(x-x1)] Lets work it out.
Y+3=1/3(x-9)
Y+3=1/3x-3
Subtract 3 from both sides so
Y=1/3x
Answer:46 by 46 that is how much for two tshirts will cost
Answer:
QT = 45
Step-by-step explanation:
ST = 65
SP = 26
RQ = 30
QT = 4x - 3
Given that ∆STR is similar to ∆PTQ, therefore:

Plug in the values

Solve for x


Cross multiply


Collect like terms


Divide both sides by 8


✅QT = 4x - 3
Plug in the value of x
QT = 4(12) - 3 = 48 - 3
QT = 45
